I want to use my AI Thinker ESP32 Cam, an Arduino Uno, a small fan, and a position sensor for a project. I have been able to get the items to work separately but when I try to combine them it does not work. Can I use the ESP Cam AI Thinker as the master and the Uno as the slave and control the fan?

Yes, you can do that.
But I think it is easier to use serial communication instead.
There are not many examples showing how to set an ESP32 as an I2C master.

At the moment, we don’t have any tutorials showing how to establish a serial communication.
I found this simple example that might help: https://www.programmingboss.com/2021/04/esp32-arduino-serial-communication-with-code.html
